Upcoming Artemis 2 Mission Reflects Apollo 8 Mission

Artemis 2 expects to take humans farther than any has yet traveled, >390,000 km, with 1st woman and 1st from outside USA, launching NET 5 Feb; Apollo 8 is recognized for being 1st to bring humans beyond Earth orbit, traveling 377,349 km away; Artemis 2 Astronauts will be absent communication with Earth ~45 minutes during Moon far side flight, learning from Apollo 8 Astronauts who experienced this 10 times in 20 orbits; ~1/4 of Earth humans saw television broadcast before Trans Earth Injection 25 December 1968, presaging Artemis 2 laser-based Orion Artemis II Optical Communications System “O2O” with 4K ultra-HD video livestream

Moon Olympics as Overarching Concept

Olympic-class spirit would be appropriate in any discussion of a 2nd Moon race, fostering sports-like excellence in a mode of international friendship during competition; challenges of complexity arise for all, whether SpaceX with a multi-stage system, Blue Origin announcing a new robotic cargo Moon lander prior to its Mark 1, SLS and Orion moving toward launch, or China now test-firing its human-rated long March 10 twice; since People’s Republic of China 2013 Chang’E-3 landing, China has shared Moon rocks / research internationally
